Humans have searched for the secret to immortality for thousands of years. For some people today, that quest includes things like sleeping in a hyperbaric chamber, experimenting with cryotherapy or blasting oneself with infrared light.

Most aging experts are skeptical that these actions will meaningfully extend the upper limits of the human life span. What they do believe is that by practicing a few simple behaviors, many people can live healthier for longer, reaching 80, 90 and even 100 in good physical and mental shape. The interventions just aren’t as exotic as transfusing yourself with a young person’s blood.

“People are looking for the magic pill,” said Dr. Luigi Ferrucci, the scientific director of the National Institute on Aging, “and the magic pill is already here.”

Below are seven tips from geriatricians on how to add more good years to your life.

The number one thing experts recommended was to keep your body active. That’s because study after study has shown that exercise reduces the risk of premature death.

Physical activity keeps the heart and circulatory system healthy and provides protection against numerous chronic diseases that affect the body and mind. It also strengthens muscles, which can reduce older people’s risk of falls.

“If we spend some of our adult years building up our muscle mass, our strength, our balance, our cardiovascular endurance, then as the body ages, you’re starting from a stronger place for whatever is to come,” said Dr. Anna Chang, a professor of medicine specializing in geriatrics at the University of California, San Francisco.

The best exercise is any activity you enjoy doing and will stick with. You don’t have to do a lot, either — the American Heart Association recommends 150 minutes of moderate-intensity exercise per week, meaning just walking a little more than 20 minutes a day is beneficial.

The experts didn’t recommend one specific diet over another, but they generally advised eating in moderation and aiming for more fruits and vegetables and fewer processed foods. The Mediterranean diet — which prioritizes fresh produce in addition to whole grains, legumes, nuts, fish and olive oil — is a good model for healthy eating, and it’s been shown to lower the risk of heart disease, cancer, diabetes and dementia.

Some experts say that maintaining a healthy weight is important for longevity, but to Dr. John Rowe, a professor of health policy and aging at Columbia University, that’s less of a concern, especially as people enter old age. “I was always more worried about my patients who lost weight than my patients who gained weight,” Dr. Rowe said.

Sleep is sometimes overlooked, but it plays a major role in healthy aging. Research has found that the amount of sleep a person averages each night is correlated with their risk of death from any cause, and that consistently getting good quality sleep can add several years to a person’s life. Sleep appears to be especially important for brain health: A 2021 study found that people who slept less than five hours a night had double the risk of developing dementia.

“As people get older, they need more sleep rather than less,” said Dr. Alison Moore, a professor of medicine and the chief of geriatrics, gerontology and palliative care at the University of California, San Diego. Seven to nine hours is generally recommended, she added.

This goes without saying, but smoking cigarettes raises your risk for all kinds of deadly diseases. “There is no dose of cigarette smoke that is good for you,” Dr. Rowe said.

We’re starting to understand how bad excessive alcohol use is, too. More than one drink per day for women and two for men — and possibly even less than that — raises the risk for heart disease and atrial fibrillation, liver disease, and seven types of cancer.

Nearly half of American adults have hypertension, 40 percent have high cholesterol and more than one-third have pre-diabetes. All the healthy behaviors mentioned above will help manage these conditions and prevent them from developing into even more serious diseases, but sometimes lifestyle interventions aren’t enough. That’s why experts say it’s critical to follow your doctor’s advice to keep things under control.

“It’s not fun to take the medications; it’s not fun to check your blood pressure and check your blood sugar,” Dr. Chang said. “But when we optimize all those things in a whole package, they also help us live longer, healthier, better lives.”

Psychological health often takes a back seat to physical health, but Dr. Chang said it’s just as important. “Isolation and loneliness is as big a detriment to our health as smoking,” she said, adding that it puts us “at a higher risk of dementia, heart disease, stroke.”

Relationships are key to not only living healthier, but also happier. According to the Harvard Study of Adult Development, strong relationships are the biggest predictor of well-being.

Dr. Rowe tells the medical students he teaches that one of the best indicators of how well an elderly patient will be faring in six months is to ask him “how many friends or family he’s seen in the last week.”

Even thinking positively can help you live longer. Several studies have found that optimism is associated with a lower risk of heart disease, and people who score highly on tests of optimism live 5 to 15 percent longer than people who are more pessimistic. That may be because optimists tend to have healthier habits and lower rates of some chronic diseases, but even when accounting for those factors, the research shows that people who think positively still live longer.

If you had to pick one healthy practice for longevity, “do some version of physical activity,” Dr. Moore said. “If you can’t do that, then focus on being positive.”

Six Fascinating Facts about Aging

Unless you die young, you’re likely to grow old. And although this is not without challenges, there are numerous upsides including financial security, learning to say “no” to people, experiences or activities you simply don’t enjoy, and the resultant contentment that comes from being true to yourself.

I found the following facts interesting, and hope you do too.

Old Age Isn’t (Just) a Modern Phenomenon

A common misconception is that our predecessors lived brutish lives cut short by disease and war. While modern medicine has certainly expanded life expectancy, many people in the past lived as long as people live today. For example, some ancient Roman offices sought by politically ambitious men couldn’t even be held until someone was 30

When scientists analyzed the pelvis joints (a reliable indicator of age) in skeletons from ancient civilizations, they found that many people lived long lives. One study of skeletons from Cholula, Mexico, between 900 and 1531 CE found that a majority of specimens lived beyond the age of 50. Low life expectancy in ancient times was more the result of high infant mortality rates than of people living unusually short lives. Modern science has helped more humans survive our vulnerable childhood years and life expectancy averages have risen as a result.

It’s a Myth that Older People Require Less Sleep

The amount of sleep each of us needs is only altered during childhood and adolescence as our bodies require more energy to do the tough work of growing. Once we’re in our 20s, humans require the same amount of sleep per night for the rest of our lives (though the exact number of hours differs from person to person). In fact, the elderly are more likely to be sleep-deprived because they receive lower-quality sleep caused by sickness, pain, medications, or a trip or two to the bathroom. This can be why napping during the day becomes more common as we grow older.

Some of Our Bones Never Stop Growing

While we’re likely to get shorter as we age, some bones keep growing. A 2008 study for Duke University revealed that skull bones continue to grow, with the forehead moving forward and cheek bones moving backward. Unfortunately, this imperceptible bit of facial movement exacerbates wrinkles, because as the skull shifts forward, the overlying skin sags.

The pelvis also keeps growing throughout our lives. Scientists analyzing the pelvic width of 20-year-olds compared to 79-year-olds found a 1-inch difference in width, which adds an additional 3 inches to your waistband. That means our widening in the middle as we age isn’t our imagination — or about a slower metabolism.

Pupils Get Smaller As We Age

While our hips get bigger, our pupils get smaller. The human pupil is controlled by the circumferential sphincter and iris dilator muscles, which weaken as we get older. Because of this loss of muscle function, pupils get smaller as we age, and are also less responsive to light. Smaller pupils make it harder to see at night (hello, reading a menu in a dark restaurant?!), so people in their 60s need three times as much light to read comfortably as people in their 20s.

Other eye changes include an increased likeliness of presbyopia, or farsightedness (often be resolved with readers), and cataracts, a clouding of the eye’s lens. In fact, half of people over the age of 80 will have experienced a cataract of some kind.

Older People Have a Stronger “Immune Memory”

Although the body experiences some slowing down as we age, growing old isn’t all bad news. Researchers from the University of Queensland found that older people had stronger immunities than people in their 20s, as the body keeps a repository of illnesses that can stretch back decades. This extra line of defense begins to drop off in our 70s and 80s, but until then, our bodies generally just get better and better at fighting off disease due to biological experience. Additionally, as we age we experience fewer migraines, the severity of allergies declines, and we produce less sweat. Older people also exhibit higher levels of “crystalized intelligence” (or what some might call “wisdom”) than any other age group.

The Atoms That Make Up All of Us Are Already Billions of Years Old

If age is just a number, in the cosmic view human age is rather insignificant. The atoms that make up the human body are already billions of years old. For example, hydrogen — one of the key components of our bodies — formed in the Big Bang 13.7 billion years ago. Likewise, carbon, the primary component of all known life, formed in the fiery cauldron of stars at least 7 billion years ago.

Which, comparatively speaking, makes us all universally young. I find that strangely comforting!

What’s In a Name?

Is anyone else watching the middle-aged adventures of 55-year-old Carrie et. al. in And Just Like That? I’m enjoying it (after the shock of the first episode) but I have to wonder:

Does the world need a new definition for the no-longer-young but not-yet-old?

Photo by Bella Zhong on Pexels.com

To my mind, “middle-aged” is ’40s-’50s, and “elderly” is ’80’s-90’s. (Although from where I sit, 40 still seems relatively young.) So where do the ’60s-’70s fit in?

If you’re 60+, you’re not in the middle since we’re unlikely to live to 120. But is it “elderly”? Most sexagenarians I know are healthy, energetic, and reasonably current with contemporary culture thanks to technology. “Elderly” sounds frail rather than older and (hopefully) wiser.

I suggest that those of us in our ’60’s and 70’s deserve a designation besides Baby Boomers. “Post-ers” because we’re post-middle-age? “Pre-elderly”? Any proposals from the floor?

Back to the show. Some of Carrie’s outfits seem a little silly (“mutton dressed as lamb”) and I wish they’d let her look a bit more age-appropriate without being staid. But I applaud a world in which a show about older women (and their sex lives) still generates cross-generational interest. Maybe that’s all the progress we need.

Good News Monday: Your Aging Brain is a Better Brain

Better brainpower with age: Some mental abilities actually improve after turning 50!

by Study Finds

WASHINGTON — Think it’s all downhill for your brain after you hit 50? Think again. Like a fine wine, some mental skills such as concentration and paying attention to detail, believe it or not, actually improve with age.

The exciting discovery could lead to better therapies for Alzheimer’s disease, say scientists.

“These results are amazing, and have important consequences for how we should view aging,” says senior investigator Michael Ullman, PhD, a professor in the Department of Neuroscience at Georgetown University and director of its Brain and Language Lab., in a statement.

The study of hundreds of older people found two key brain functions get better from our 50s onwards. They include attending to new information and focusing on what’s important in a given situation. They underlie memory, decision making and self control, and are even vital in navigation, maths, language and reading.

“People have widely assumed attention and executive functions decline with age, despite intriguing hints from some smaller-scale studies that raised questions about these assumptions, but the results from our large study indicate that critical elements of these abilities actually improve during aging, likely because we simply practice these skills throughout our life,” says Ullman. “This is all the more important because of the rapidly aging population, both in the U.S. and around the world.”

Ullman believes deliberately improving these abilities will help protect against brain decline.

Dementia cases worldwide are expected to triple to around 150 million by 2050. With no cure in sight, there is an increasing focus on lifestyle changes that reduce the risk.

For their study, the international team looked at three separate components of attention and executive function in 702 participants ages 58 to 98, when cognition often changes the most. The brain networks are involved in alerting, orienting and executive inhibition. Each has separate characteristics and relies on different regions, neurochemicals and genes, suggesting unique aging patterns. Alerting is characterized by a state of enhanced vigilance and preparedness in order to respond to incoming information. Orienting involves shifting brain resources to a particular location. The executive network shuts out distracting or conflicting information.

“We use all three processes constantly. For example, when you are driving a car, alerting is your increased preparedness when you approach an intersection. Orienting occurs when you shift your attention to an unexpected movement, such as a pedestrian,” explains first author Dr Joao Verissimo, of the University of Lisbon, “And executive function allows you to inhibit distractions such as birds or billboards so you can stay focused on driving.”

Remarkably, only alerting abilities were found to decline with age. In contrast, both orienting and executive inhibition actually got better. The latter two skills allow people to selectively attend to objects, and improve with lifelong practice, explain the researchers. The gains can be large enough to outweigh any underlying neural reductions.

In contrast, alerting may drop off because this basic state of vigilance and preparedness does not get better with implementation.

“Because of the relatively large number of participants, and because we ruled out numerous alternative explanations, the findings should be reliable and so may apply quite broadly,” says Dr Verissimo, “Moreover, because orienting and inhibitory skills underlie numerous behaviors, the results have wide ranging implications.”

“The findings not only change our view of how aging affects the mind, but may also lead to clinical improvements, including for patients with aging disorders such as Alzheimer’s disease.” adds Ullman.

The findings are published in the journal Nature Human Behavior.

Good News Monday: Housework = Brain Work

According to the study below. So if you sit on your butt while your partner does the housework, here’s good reason to think twice!

Doing household chores can actually give you a bigger brain

StudyFinds.com

TORONTO, Ontario — Have you been putting off your spring cleaning or just saving some tedious chores for a rainy day? A new study may provide the motivation you need, especially for seniors. Researchers in Toronto find older adults who perform household chores have larger brains — a key measure of good cognitive health.

“Scientists already know that exercise has a positive impact on the brain, but our study is the first to show that the same may be true for household chores,” says Noah Koblinsky, lead author of the study, Exercise Physiologist and Project Coordinator at Baycrest’s Rotman Research Institute (RRI) in a media release.

“Understanding how different forms of physical activity contribute to brain health is crucial for developing strategies to reduce the risk of cognitive decline and dementia in older adults.”

Researchers at Baycrest Hospital examined 66 mentally healthy older adults during their study. Each participant took part in three assessments, a health evaluation, structural brain imaging, and a cognitive test. Results reveal older people who spend more time doing chores have greater brain volume, regardless of how much they exercise. These chores ranged from cleaning, to cooking, to going outside and working in the yard.

How do chores keep the brain healthy?

Although most people probably aren’t fond of doing chores, the team finds they’re likely helping the brain in several ways. First, study authors believe chores have a similar effect as low-intensity aerobic exercise — which benefits the heart and blood vessels.

Chores also push the mind to plan and organize, which promotes the formation of new neural connections over time. Lastly, researchers say chores help older adults become less sedentary. Previous studies have revealed how sitting and being less active can lead to poor health and cognitive decline.

“Besides helping to guide physical activity recommendations for older adults, these findings may also motivate them to be more active, since household chores are a natural and often necessary aspect of many people’s daily lives, and therefore appear more attainable,” says senior author Dr. Nicole Anderson, Senior Scientist at the RRI.

The study appears in the journal BMC Geriatrics.

Dementia or Alzheimer’s?

mental-health-3285627_640

A few days ago DH and I watched the lovely and touching movie, The Leisure Seeker, which reminded me to share an interesting article.

My parents’ generation used to refer to this health issue as “losing your marbles”, which sounds more charmingly benign than the sad reality of cognitive decline. Whether you’re concerned for yourself, an aging relative, or a friend, I hope you’ll find it informative.

Dementia vs. Alzheimer’s: Which Is It? How to understand the difference — and why it matters

by Kathleen Fifield, AARP, June 25, 2018 

The terms “dementia” and “Alzheimer’s” have been around for more than a century, which means people have likely been mixing them up for that long, too. But knowing the difference is important. While Alzheimer’s disease is the most common form of dementia (accounting for an estimated 60 to 80 percent of cases), there are several other types. The second most common form, vascular dementia, has a very different cause — namely, high blood pressure. Other types of dementia include alcohol-related dementia, Parkinson’s dementia and frontotemporal dementia; each has different causes as well. In addition, certain medical conditions can cause serious memory problems that resemble dementia.

A correct diagnosis means the right medicines, remedies and support. For example, knowing that you have Alzheimer’s instead of another type of dementia might lead to a prescription for a cognition-enhancing drug instead of an antidepressant. Finally, you may be eligible to participate in a clinical trial for Alzheimer’s if you’ve been specifically diagnosed with the disease.

What It Is

Dementia 

In the simplest terms, dementia is a nonreversible decline in mental function.

It is a catchall phrase that encompasses several disorders that cause chronic memory loss, personality changes or impaired reasoning, Alzheimer’s disease being just one of them, says Dan G. Blazer, M.D., a professor of psychiatry at Duke University Medical Center.

To be called dementia, the disorder must be severe enough to interfere with your daily life, says Constantine George Lyketsos, M.D., director of the Johns Hopkins Memory and Alzheimer’s Treatment Center in Baltimore.

Alzheimer’s

It is a specific disease that slowly and irreversibly destroys memory and thinking skills.

Eventually, Alzheimer’s disease takes away the ability to carry out even the simplest tasks.

A cure for Alzheimer’s remains elusive, although researchers have identified biological evidence of the disease: amyloid plaques and tangles in the brain. You can see them microscopically, or more recently, using a PET scan that employs a newly discovered tracer that binds to the proteins. You can also detect the presence of these proteins in cerebral spinal fluid, but that method isn’t used often in the U.S.

How It’s Diagnosed

Dementia

A doctor must find that you have two or three cognitive areas in decline.

These areas include disorientation, disorganization, language impairment and memory loss. To make that diagnosis, a doctor or neurologist typically administers several mental-skill challenges.

In the Hopkins verbal learning test, for example, you try to memorize then recall a list of 12 words — and a few similar words may be thrown in to challenge you. Another test — also used to evaluate driving skills — has you draw lines to connect a series of numbers and letters in a complicated sequence.

Alzheimer’s 

There’s no definitive test; doctors mostly rely on observation and ruling out other possibilities.

For decades, diagnosing Alzheimer’s disease has been a guessing game based on looking at a person’s symptoms. A firm diagnosis was not possible until an autopsy was performed.

But that so-called guessing game, which is still used today in diagnosing the disease, is accurate between 85 and 90 percent of the time, Lyketsos says. The new PET scan can get you to 95 percent accuracy, but it’s usually recommended only as a way to identify Alzheimer’s in patients who have atypical symptoms.

“Anti”-Aging

Allure magazine has recently reported that they’ll no longer use the term “anti-aging”. It’s about time.

Since we’ve only got two options — getting older or checking out — there’s not much point in fighting the inevitable. Instead, let’s embrace some of the positives and enjoy being our best selves.

IMG-0025 (1)

Antiques are so much more interesting than newbies!

The List

1. YOUR DOUBLE CHIN DISAPPEARS. With the passing years, fat pads under our chins usually get smaller as our faces become less round. (Bonus: more visible cheekbones!) So if you’re considering a fat removal procedure in your 20’s or 30’s, you should probably wait.

2. YOU’RE HAPPIER. According to a study in the Journal of Clinical Psychology, happiness steadily increases from your 20’s to your 90’s as anxiety, depression and stress levels tend to go down.

3. YOU CAN WAVE GOODBYE TO THE BAGS UNDER YOUR EYES. When we’re younger, these are often fatty deposits. In older women, they’re more likely caused by fluid retention, which decreases as we go about our day.

4. SEX IMPROVES. Caveat: The study they cite in the magazine contrasts higher levels of satisfaction for women in their 40’s and 50’s vs. women in their early 20’s. Older women know their bodies better, are more likely to ask for what they want, and may be more spontaneous. (Note: no mention of post-menopausal issues, though.)

5. YOUR SKIN IS GLOWIER. Again, they’re talking 30’s-50’s, when moisture levels are highest and problems such as acne tend to resolve themselves. Moisture levels drop as hormones and hydration decrease, so 60+ skin often needs extra help.

6. YOU’LL SAVE ON WAXING. As testosterone dips in your 40’s, body hair starts to be lighter and thinner. Post-menopause, skin becomes thinner and waxing may be more irritating than a gentler process such as sugaring. Or, fuhgeddaboudit.

7. YOU’RE MORE OPEN-MINDED. A University of Michigan study found that women in their 50’s were more empathetic than those who were younger. Mature people may have strong opinions but we’re also more likely to understand other points of view.

Beauty Round-Up

As a public service to those of you who don’t have the time, inclination, or mind-numbingly long plane flights to read magazines, here are seven items that caught my eye recently.

FullSizeRender 4

  • A hot bath burns as many calories as a 30-minute walk. This one really resonates with my inner sloth.
  • Cure for cellulite? The BelleCore Body Buffer, $149, is said to reduce water retention while buffing the skin to release tension and stretch the tough tissue that holds fat cells in place, creating that dreaded dimpled effect. I’d try it myself except that 1) I’ve spent far too much money this month, and 2) my butt and thighs are already flawless. Yeah, right.
  • The Big Five ingredients we need to improve our skin:
    1. Vitamin C, the powerful antioxidant that supports healthy collagen and fights free radicals that break it down. Check the concentration; anything cheap probably has too little to be effective.
    2. Retinol, the “miracle” ingredient that fights acne, smooths and reduces wrinkles and works wonders on sun-damaged skin. Best used at night and be sure to use sunscreen daily.
    3. Hyaluronic Acid (HA), which acts like a sponge to pull moisture from the air into the skin. Caveat: In a really dry climate, it can work in reverse, so slather on a rich moisturizer on top to prevent water loss.
    4. Alpha Hydroxy Acids (AHAs) such as glycolic acid increase cell turnover and inhibit enzymes that destroy collagen and elastin to treat fine lines, dullness and blackheads. Without SkinMedica’s GlyPro line, I’d probably look about 80.
    5. It may seem counterintuitive but oils work on both oily and dry skin. On oily complexions, face oil can signal the skin to stop overproducing sebum. For dry skin, layer oil over your HA serum and massage it in. Look for one that’s cold pressed (like a good olive oil) because heat can destroy its active properties.
  • A cluttered environment decreases self-control, increasing the likelihood of impulsive spending, according to a study in the Journal of Consumer Research. I’m cleaning up my desk RIGHT THIS MINUTE.
  • More vitamin D correlates with longer telomeres, the protective DNA sequences at the end of chromosomes. Shortened/broken telomeres are linked to blotchy skin, grey or thinning hair, deep wrinkles and other age-related consequences. Salmon, anyone??
  • Layer skin care products in order of “heaviness”. After cleansing and drying your skin (to reduce potential irritation), pat on your serum and let it dry before you layer on anything else. Next, massage in your facial oil. Then apply a rich moisturizer to lock in hydration. Sunscreen is your final product during the day, of course.
  • Tips for growing stronger nails:
  1. File in one direction from the outside to the center on both sides, using a file with 240 to 600 grit. Never metal.
  2. Don’t peel off your gel manicure or chipped polish. But you already knew that.
  3. Dry nails are more likely to break. Rub lotion and cuticle oil in throughout the day to get blood flowing and help stimulate cell regeneration.
  4. An almond shape is the strongest.
  5. According to dermatologists, the only supplement proven to work is biotin (2.5 mg/day, but check with your own doctor). Some recommend MSM, a form of sulphur, to help bind keratin in hair and nails.
  6. It takes six months for a nail to regrow.

By the way, people who make their bed in the morning are 19% more likely to get a good night’s beauty sleep.

Stay gorgeous! xx
